Phase boundaries in lipid-cholesterol mixtures determined by spin-label ESR. Phase boundaries are indicated by dotted lines; solid lines are tie-lines. (A) Temperature-composition binary phase diagram: gel-liquid ordered (Lβ-Lo) phase boundaries in PSM/Chol binary mixtures. (Data from [171]) (B) Constant-temperature ternary phase diagram: Gel-liquid crystalline (Lβ-Lα) phase boundaries in DPPC)/dilauroyl PC/Chol ternary mixtures at 24 °C. The x-axis XPCDPPC) is the mole fraction of DPPC, relative to total PC (DPPC+dilauroyl PC). The y-axis represents the mole fraction of Chol, relative to total PC. Actual mole percentages of Chol (Xchol) are indicated for the points at the ends of the tie lines. (Adapted from [173]).
